Abstract
A method for determining an expansion coefficient of a test material comprises: receiving first image data of a compound material, wherein the compound material comprises a plate and a layer of the test material, which is attached to the plate; receiving second image data of the compound material, which has been exposed to an environmental condition, before the second image data has been recorded; determining a measured deformation of the compound material by comparing the first image data and the second image data; and performing a simulated deformation of a model of the compound material exposed to the environmental condition and determining the expansion coefficient of the test material by varying the expansion coefficient until the simulate deformation conforms to the measured deformation.
